A source with knowledge of Wilson’s statements said the officer had told investigators that Brown had struggled for Wilson’s pistol inside a police SUV and that Wilson had fired the gun twice, hitting Brown once in the hand. Later, Wilson fired additional shots that killed Brown and ignited a national controversy.

The St. Louis medical examiner, Dr. Michael Graham, who is not part of the official investigation, reviewed the autopsy report for the newspaper. He said Tuesday that it “does support that there was a significant altercation at the car.”
